Hello Alderson, Jon,
Here are some steps you can use to troubleshoot this
- Microsoft Edge Extension Store Reachability
Even if Chrome works, Edge uses a different store (Microsoft Edge Add-ons). Check if access to the following domain is blocked, redirected, or intercepted:
https://microsoftedge.microsoft.com/addons
Try this:
- Visit the URL above directly in Edge. Can you browse the store without any redirection errors?
- Open Developer Tools (F12) → go to the Network tab → then try installing the plugin again and watch for failed requests or status codes (403, 407, etc.)
- Group Policy / Endpoint Security Blocking Extension Install
Check if a Group Policy or endpoint security rule is:
- Preventing Edge extension installs
- Restricting it to specific domains or IDs
Press Windows + R, type in gpedit.msc and enter
Navigate to Computer Configuration > Administrative Templates > Microsoft Edge > Extensions
Check for any policy that might block you from download the plugin
Also check in registry editor
Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge\ExtensionInstallBlocklist
or HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Edge
- Try Local Admin with No Network Policies Applied
You mentioned you haven't tried using a local admin account. This is highly recommended to test next.
Log in with a local admin
Disconnect from the domain (if possible)
Try installing the extension in Edge
This can help determine if a domain policy, security suite, or inherited restriction is at play
- Edge Profile or Cache Issues
Even though you reset the browser, there may be Edge profile-level issues or corrupted cache affecting the extension download.
Try:
Creating a brand new Edge profile (Settings → Profiles → Add profile)
Then attempt the install from that new profile
Hope this help with your issue.
Hello, Alderson, Jon
Thank you for your feedback. I understand that you are having trouble installing the extension. Here are some troubleshooting solutions:
This is the most likely cause, especially in an AD environment. There may be specific GPOs for the Edge browser rather than Chrome that restrict the installation or download of extensions.
- On the affected computer, open the Edge browser, enter edge://policy/ in the address bar, and press Enter. This will display all active policies applied to Edge. Carefully check for any policies related to extension installation, download paths, security settings, or proxies.
Run the gpresult /r command to view group policies applied to users and computers.
Run the gpresult /h C:\report.html command to generate a detailed HTML report, then open it. In the report, look for policies related to “Microsoft Edge,” particularly the following categories:
Computer Configuration\Administrative Templates\Microsoft Edge\Extensions
Computer Configuration\Administrative Templates\Microsoft Edge\Downloads
User Configuration\Administrative Templates\Microsoft Edge\Extensions
User Configuration\Administrative Templates\Microsoft Edge\Downloads
Look for policies such as “Block installation of extensions,” “Allow specific extensions,” “Configure download directory,” and “Scan download files for malware.”
Damaged Edge browser internal settings or profile
Even though you reset the browser, sometimes the reset may not be thorough enough, or specific profiles may still have issues.
Try a new Edge profile: In Edge, go to edge://settings/profiles, try adding a brand-new profile (without logging into any Microsoft account), then switch to that profile and see if you can install the Keeper plugin. This can rule out damage to the current user profile.
- You plan to try logging in and installing using a local administrator account. If successful: This strongly indicates the issue is related to domain user profiles, Group Policy Objects (GPOs) applied to domain users, or domain user permissions. You can further investigate permission differences between domain users and local administrators, or confirm which GPOs are applied exclusively to domain users.
If it fails: This means the issue is more widespread and may be related to the computer's configuration itself (system-level GPOs, system-level security software, the Edge installation itself), rather than just the user profile or domain user permissions.
I look forward to your feedback.
Best regards

At one of our clients , several users have reported that the keeper extension has stopped working. When clicking the extension icon in Edge it does nothing. The only current way of resolving the issue is to remove and reinstall. But that requires admin approval , which is becoming inconvenient. Has this issue been seen elsewhere? Many thanks Rob
Has anyone else opened the Keeper extension only for it to display a small white box? Closing out of all my browsers' windows and re-opening them seems to do the trick, but I get several help desk calls a day from people needing help with this exact issue.
Just wondering if there's a more permanent fix to this or if it's an issue on Keepers end?
